Mean-Median Score measures whether Democratic vote shares are distributed symmetrically across districts. A value close to 0 suggests balance.
Efficiency Gap measures “wasted votes” - votes for losing candidates plus votes beyond what’s needed to win. Positive values indicate more wasted Democratic votes (Republican advantage).
